Thread: Find maximum point of curve graph

Hi,

when finding maximum point of graph, where do I look at? The y axis or the x axis?
Also, the answer should be "x=7" (for example), am I right?

Thank you

A point has always 2 coordinates if you're working in a plane, so a maximum could be for example .

Hmm, but the question didn't state for the coordinates of maximum point of the curve, so I thought the answer would be different. Am I wrong?

But for example can't represent a point, it represents a line (parallel to the y-axis).

Yea, I will write the answer in coordinates then

Thanks a lot

Btw, how do I find the equation of line of symmetry if the line (line of symmetry) itself is in the y axis ? Which number do I take?

Do you mean the axis itself? It's just .

Yes. Thanks for the quick reply =)

You're welcome!
